Title: Check valve
Inventor: YAMADA YUTAKA
IPC: F16K15/03
Filed: 1979-06-13
Abstract: PURPOSE: To reduce the generation of water hammer action and diminish flow resistance with the valve being opened by improving the spring structure of the check valve of swing type.  
     CONSTITUTION: In this check valve, coil spring 7 for urging a valve body 1 fastened to a valve shaft 5 in the closed direction has spring constant which is set to a specified small value within an effective range in such a manner that the rotational moment becomes sufficient large level while the valve is closed and small level while the valve is opened. Thus, when the pumping power is interrupted, delay in closing is small, presure rise by water hammer is as small as undetectable and it becomes possible to eliminate noise caused by the water hammer and failure of the valve. Furthermore, since the spring 7 for urging the valve body 1 in the closed direction has small spring constant, the valve body 1 is fully opend with ease by increasing flow rate and loss of head can be held at very small level due to that there is caused no large change in current direction.

Title: Semiconductor type pressure sensor
Inventor: KATOU YUKIHIRO
IPC: G01L9/00
Filed: 1988-03-29
Abstract: PURPOSE:To achieve a higher reliability while eliminating leakage of a sealed liquid, by setting a mounting position of a sealing member to seal up the sealed liquid between the sealed liquid and a pressure medium to lower a burden on the sealing member. CONSTITUTION:A spherical steel ball valve 16 is provided to seal up a silicone oil 1e, pressed securely with a screw 17 and in contact with a pressure medium on the surface thereof 17 opposite to the surface thereof contacting the screw 17 just as a diaphragm 1b does. Here, as the valve 16 sealing up the oil 1e and the screw 17 receive a pressure P (the arrow B) from the pressure medium side equal to that P (the arrow A) received from the oil 1e side, there is little difference between pressure on the pressure medium side of the valve 16 and the screw 17 and that on the oil 1e side thereof. Thus, even when several hundreds of atm works on the diaphragm 1b, the valve 16 and the screw 17 receive a pressure of several hundreds of atm from the pressure medium on the arrow B side likewise thereby achieving a higher reliability as sensor while eliminating leakage of the oil 1e outside.

Filed: 1983-04-27
Abstract: PURPOSE:To make a demand measurement such as of AC current and electric power easy by obtaining an output voltage proportional to a DC input at a time limit characteristic to be optionally selected. CONSTITUTION:A subtractor 1 calculates an output proportional to the difference between an input voltage Ei and an output voltage Eo and inputs the output to a pulse width modulating circuit 2. The modulating circuit 2 outputs a pulse having a duty ratio proportional to the output of the subtractor 1. A counter 4 counts up pulses of an oscillation circuit 3 when the output of the modulating circuit 2 is the H level and counts down the pulses at the L level. The output of the counter 4 is converted into an analog value by a D/A converter 5 and outputted to output terminals 10, 11 through maximum and minimum value holding circuits 8, 9. The time limit characteristic of the output voltage can be easily set up by changing the constants of respective circuits 1-5. If an AC/DC transducer is connected to the input side, a demand measurement such as of AC current and electric power can be easily obtained.

Abstract: PURPOSE:To control the elution of an active component, in a microcapsule obtained by forming an active component layer containing an active component on the periphery of a small particle nucleus and coating the active component layer with an elution control film, by forming the small particle nucleus so as to control the discharge of a core substance exerting effect on the permeability of the elution control film. CONSTITUTION:In a microcapsule obtained by forming an active component layer containing an active component on the periphery of a small particle nucleus and coating the same with an elution control film, the small particle nucleus controls the discharge of a core substance (e.g. monosaccharide) exerting the effect on the permeability of the elution control film. Further, the elution control film is composed of composite structural latex consisting of a core composed of an ethyl acrylate/methyl methacrylate/2-hydroxyethyl methacrylate copolymer and a shell composed of a hydrogel. That is, the elution of the active component is controlled by controlling the elution of the core substance and this method can contribute to the production of a sustained release microcapsule containing a water-soluble polymeric active component such as protein or polypeptide.
